API Specific Gravity of Petroleum Products – ASTM D, D, D, D | Lawler Manufacturing
Density, relative density, or API gravity is a factor governing the quality and pricing of crude petroleum. However, this property of petroleum is an uncertain indication of its quality unless correlated with other properties.
Density is an important quality indicator for automotive, aviation and marine fuels, where it affects storage, handling and combustion. The apparatus can also be used for testing the specific gravity of water and brine, according to ASTM D, test method D.
The sample is brought to a specified temperature placed in a constant temperature bath to avoid excessive temperature variation during the test and a test portion is transferred to a hydrometer cylinder that has been brought to approximately the same temperature.
The appropriate hydrometer and thermometer, also at a similar temperature, are lowered into the test portion and allowed to settle. After temperature equilibrium has been reached, the hydrometer scale is read, and the temperature of the test portion is taken.
The d2287 hydrometer reading is corrected for the meniscus effect, the thermal glass expansion effect, alternate calibration temperature effects and then reduced to the reference temperature by means of the volume correction factors or tables as applicable by use of the appropriate adjunct to ASTM D guide for petroleum measurement tables API MPMS Chapter A TLC refrigerator circulates a cold flow through the double walls of the cylinders. The PTFE asgm ensure fast drainage and cleaning of the tube.
The easy detachable leakage tray prevents that portions of the sample are spilled on the workbench. The rack offers full view on the hydrometer. Our special support eliminates the problem of mounting brackets or portions of a thermostatic bath blocking the view.

The measuring set-up contains three glass cylinders with lids, a support, and a TLC circulator. Our system offers an interesting price advantage compared to other solutions based on a combination of a thermostatic bath and an external chiller. Please contact our sales team sales tamson.
